ETERNAL-COMBUSTION ENGINE.

Patented Mar. 25, 1919.

Application filed October 22, 1917. Serial No. 197,761.

To all whom it may concern:

Be it known' that I, HAROLD E. MONTA- GUE, a citizen of the UnitedStates, and a resident of Philadelphia, in the county of Philadelphiaand State of Pennsylvania, have invented certain new and useful Improiements in Internal Combustion F.ngines, of which the following is aspecification.

The present invention relates to improvements upon the inventiondescribed and claimed in Letters Patent No. 1,227,551 of May 22nd, 1917,to the applicant, for improvements in internal combustion engines, andits principal object is to improve the results attained by the inventionof said patent, especially in respect to the use of low grade fuel oilsand in respect to the distribution and application of heat, whilemaintaining all the advantages incident to its use.

The improvements constituting the present invention will be claimed atthe end hereof but will be first described in connection with theembodiment of it chosen from among other embodiments for the sake ofillustration in the accompanying drawings in which engine areillustrated respectively at A, B, V

C and D and are illustratedas constructed in pairs. The inlet to thecylinders A and B is indicated at 1, and the inlet to the cylindeIs Cand D is indicated at 2. The ex haust from the cylinder A is at 3, theexha'ust from the cylinder B is at 1, the exhaust from the cylinder C isat 5, and the exhaust from the cylinder D is at 6. 7, is a carbureter towhich liquid fuel is supplied as by a pipe 8 from some outside source.9, is an elongated chamber communicating with the carbureter and withthe inlet ports/1 and 2 of the engine. 10 is an exhaust compartmentwithin which the chamber 9 is inclosed and which receives the exhaustgases from the engine at a pluraiity of ports 3, 4, 5, and 6,distributed along the chamber 9. In general the foregoing is adescription of apparatus shown and described in the patent abovereferred to.

11 is a wall sub-dividing the upper part of the space between theoutside of the chamber ,9 and the inside of the compartment l0 and thiswall extends from the top of the compartment 10 downward for somewhatmore than half the height of the chamber, although the exact distance isnot important. 12, is a steam generator on the wall of the compartment10 and it is shown as provided with vents 13. 14:, is a sight feed cupwhich may be employed for feeding water in regulated small quantities tothe steam generator 12 upon which it is shown as mounted. The wallll isprovided with a port 15 extending through it to the interior of thechamber 9 and this port is connected through a check valve 16 with theinterior of the steam generator 12 as by a pipe 16, shown in Fig. 3, andindicated by dotted lines in Fig. 1, although the dotted portion wouldbe removed in making the section but for clearness it is indicated. 17is an air heater consisting of a cavity in the wall of the compartment10 and to which air is supplied as by perforations 18 and from which airis delivered as by the connection 19 to the carbureter. The compartment10 is provided with two exhaust openings 20 and 21, of which one isarranged at the bottom and the other at one side, or the other as may bemost convenient in the assembly of the parts. One of these exhaustopenings, for example, the opening 20 may be used as a cutout and theother, 21, used as an exhaust proper. However, this use mav be inverted,if desired. The wall 11 is shown as thickened to accommodate the port15.

In the modification shown in Fig. 4;, the wall is thickened as at 22 andbored as indicated in dotted lines to fit it for use as a steam or waterinlet, and the pipe 16 and its fittings, shown in Fig. 3, are omitted.

In general the mode of operation of the described mechanism is correctlyset forthin said patent and in that connection the addition of dry steamfrom the generator 12 into the interior of the chamber 9 where itmingles with the dry gas improves the combustion and power of the engineand brings low fuel oils up to a high and eficient combination. In otherwords, the fuel is made readily ignitible when dry steam is mixed withit in the manner described. The suction of the engine draws some airthrough the Vents 13 and also draws dry steam from the generator 12 intothe chamber 9. It may be remarked that the ort 15 serves as a means forintroducing ight oil as by pipe 16 to prime the engine, as in starting,because when the engine is starting steam is not generated in thegenerator 12. The wall 11 divides the exhaust gases and promotes aperfect circulation and proper distribution of heat more particularly inrespect to the steam generator 12. The wall also adds strength andconstitutes a means for delivering heat to the chamber 9. Additionallythe wall affords convenient means for making ports through whichcommunication can be had with the interior of the chamber 9.

What I claim is: a

1. In an internal combustion engine and in combination with thecylinders thereof, a carbureter, an elongated chamber communicating withthe carbureter and with the inlet ports of the cylinder, an exhaustcompartment closed at its top and within which the entire chamber isinclosed and which re- Y ceives the exhaust gases from the engine at aplurality of ports distributed along the chamber, there being space allaround the chamber and between it and the compartment for thecirculation of exhaust to avoid cold chamber walls, a wall dependingfrom the closed top of the com artment and subdividing the upper part 0the space between the outside of the chamber and the inside of thecompartment, a steam generator arranged at the closed top ofthecompartment, and means for introducing steam from the easmo generatorinto the chamber, substantially as described. Y

2. In an internal combustion engine and in combination with thecylinders thereof, a

carbureter, an elongated chamber communieating with the carbureter andwith the inlet ports of the cylinder, an exhaust compartment closed atits top and within which the entire chamber is inclosed and whichreceives the exhaust gases from the engine at a plurality of portsdistributed along the chamber, there being space all around the chamberand between it and the compartment for the circulation of exhaust toavoid cold chamber walls, a ported wall depending from the closed top ofthe compartment and sub-dividing the upper part of the space between theoutside of the chamber and the inside of the compartment, a steamgenerator arranged at the closed top of the compartment, and aconnection from the steam gen-. erator through the ported wall to theinterior of the chamber, substantially as described.

3. In a device of the class described the combination of a wallinclosing. an elongated intake chamber, a second Wall spaced from andindependent of the first wall and inclosing an exhaust compartmentclosed at its top, the space between said walls permitting access forhot exhaust to the entire surface of the intake chamber, a third walldepending from the closed top of the compartment and sub-dividin theupper part of the space between the c iamber and compartment, a steamgenerator arranged on the wall at the closed top of the compartment, andmeans for introducing steam from the generator into the upper part ofthe chamber, substantiall as described.
